In 1820, Gaspard Count Sternberg published in German, the first number of a work which has been translated by the Comte de Bray, under the title of "Essai d'un Exposé Geognostico-Botanique de la Flore du Monde Primitif." Of this translation a second and third part appeared in 1823 and 1824. In these successive numbers the Count has communicated the state of his knowledge as it grew up under his hands, in consequence of his own labours and those of his friend, Baron Schlotheim. The genera, as they are successively developed in the work, are the following:—
1. Lepidodendron.—Stem scaly; the scales leaf-bearing, surrounding the stem spirally. In a subsequent number, what are here called scales, are denominated scale-like cicatrices.
